Already had base game but stuck on installing EP's

So, I already have the base game for the Sims 4. I've downloaded all the expansions that I'm wanting to install but I'm having an issues as to where I am supposed to place the information for the expansions packs in to specific folders. The directions really only say to download and install. 

This is what i'm getting :
1. Drag and drop all the folders mentioned below from this .RAR file to the folder where you installed your
The Sims 4 base game to. If you installed the Games4theworld version of the base game, by default your
installation folder will be: C:\Program Files (x86)\Electronic Arts\The Sims 4\
A popup will appear, telling you the files and folders already exist. Choose "Copy and replace", to replace the old files
with the updated ones. Copy ALL the folders:

- __Installer
- Data
- Delta
- EP01
- FP01
- Game
- GP01
- Support

2. The game is pre-cracked with RELOADED's wonderful crack, so after copying all the folders, run the game and... ENJOY playing!

After I do this how do I run the game without Origin?

These are probably super easy dumb questions but its been a long time since of done this heh.

Hello and welcome to the Forum,

Inside the Game\Bin subfolder there is a file "TS4.exe", you should use this file to start the game.

Note that this will start the 32-bit version of the game. See step #8 of this guide here to learn about the 64-bit version of TS4:

"If you want to use the 64-bit version of The Sims 4 (which is only possible if you're using a 64-bit Windows version), we recommend you move the "The Sims 4" folder to this folder instead: C:\Program Files\ , so that your new installation location of The Sims 4 will be C:\Program Files\The Sims 4 ."
